What are 2 metamorphic minerals formed along oceanic ridges?
Minerals are not classified as metamorphic. The mid-oceanic ridges are generally considered to be areas where new basaltic crust is formed from uprising magma. The basalt is considered an igneous rock in classification.
What kinds of rocks are associated with ocean ridges?
Basalt rocks are commonly associated with ocean ridges due to the process of seafloor spreading where magma rises to the surface, cools, and solidifies. These basaltic rocks form the oceanic crust along the ridges.
Basalt is the most common magma erupted along oceanic rift systems?
Basalt is commonly erupted along oceanic rift systems due to its low viscosity and high fluidity, making it easier for the magma to flow and reach the surface. Its composition is also a result of partial melting of the Earth's mantle at mid-ocean ridges, where new oceanic crust is formed through volcanic activity. The eruption of basaltic magma at oceanic rift systems contributes to the continuous creation of new crust and plays a key role in plate tectonics.
Where is Ocean ridges generally are located?
Ocean ridges are generally located where tectonic plates are moving apart, such as along mid-ocean ridges where seafloor spreading occurs. Examples include the Mid-Atlantic Ridge and the East Pacific Rise.
What is the youngest part of earth's crust?
The youngest part of Earth's crust is found along mid-ocean ridges where new crust is continuously formed through volcanic activity. This process is known as seafloor spreading, where magma rises to the surface, cools, and solidifies to create new crust.
Why does so much basaltic magma erupt along mid-ocean ridges?
Basaltic magma erupts along mid-ocean ridges primarily due to tectonic plate divergence, which creates space for magma to rise from the mantle. As the plates pull apart, the pressure decreases, allowing the mantle rock to partially melt and form basaltic magma. The relatively low viscosity of basaltic magma facilitates its ascent, leading to frequent eruptions and the formation of new oceanic crust at these ridges. Additionally, the continuous supply of heat from the mantle ensures ongoing volcanic activity in these regions.

What type of boundary is along ocean ridges?
Constructive or divergent. The ridge formed is of basaltic rock type (though this is a generalisation), and is a source of volcanic activity. Iceland was formed as a result of the sea-floor spreading.
Where do rocks from the mid-ocean ridges come from?
Rocks from mid-ocean ridges originate from the Earth's mantle, where molten rock, or magma, rises to the surface along tectonic plate boundaries. As tectonic plates diverge, this magma erupts and solidifies, forming new oceanic crust. The ongoing process of seafloor spreading continuously adds new material to the ocean floor, resulting in the creation of basaltic rocks characteristic of mid-ocean ridges.
Which forms at mid-ocean ridges?
New oceanic crust is created along mid ocean ridges. These are areas of the earth where there is divergence or splitting of the ocean floor and basaltic magma oozes out from within the mantle to occupy the gaps and form new crusts.
What are the medial ridges along the sacrum called?
The medial ridges along the sacrum are called the sacral crest. It is a series of tubercles that represent the processes of the sacral vertebrae.
Are mid-ocean ridges located mostly along coastlines?
No, mid-ocean ridges are not located mostly along coastlines. Mid-ocean ridges are underwater mountain ranges that form where tectonic plates are pulling apart. They are located in the middle of the ocean and can extend for thousands of kilometers.
What cause the laki volcano to explode?
The Laki volcano in Iceland erupted in 1783 due to a series of fissures opening up along its flanks, releasing a large volume of basaltic lava and volcanic gases. The eruption lasted for about eight months and had devastating environmental impacts on the local and global scale.
What is MOR volcano?
MOR stands for mid-ocean ridge, which is a underwater mountain range where volcanic activity occurs. The volcanoes that form along mid-ocean ridges are typically characterized by basaltic lava flows and are an important part of the process of seafloor spreading.
Elevated ridges along the flood plain are known as?
Leeves
